IMPORTANT WARNING: Hydroxyurea can cause a severe decrease in the number of blood cells in your bone marrow. This may cause certain symptoms and may increase the risk that you will develop a serious infection or bleeding.
Stage IV colon cancer commonly spreads to the liver or the lungs. Some patients who have cancer that has spread to a single area are candidates for surgery to remove the metastases. Treatment of the liver: When itâs possible to completely surgically remove all liver metastases, surgery is the preferred treatment.
The cancer has grown through the wall of the colon and may extend into nearby tissue, but has not spread to the lymph nodes. Surgery is usually the only treatment needed for colon cancer but radiation therapy may be needed for rectal cancers. In some cases your doctor may recommend additional chemotherapy.
